Q:

How to direct my one-year old baby not to do bad things

I have a one-year old baby, she is smart and loves to try everything and anything, including putting her fingers in the electricity and tasting every possible thing she finds :)
How can I tell my child in such age not to do that or this, and deliver her the message that doing something is not right?
Sometimes I shout in her face to deliver the message (sometimes she cries when I do that), or (gently) hit her mouth or hand to tell her that she shouldn't eat or touch that...
I feel I'm doing the wrong thing, and I need advice from others with experience or knowledge.

A one year child, while quite active with the hands and legs, is in the discovery phase, everything is new and exciting. Putting things in the mouth or feeling crevices through is their way of experiencing their world.
At the same time, they are definitely aware of when their parents are happy with them and when they are not. They also try to take actions that make the parents happy or get them engaged in a positive manner with the parents.
Try to move the child away from the objects, look them in th eye and change your voice intonation (without raising it too much) to let them know if there is a behaviour you are not happy about.
Similarly praise them with a smile or hug when they do something positive, like walking or crawling, or keeping things in their right places. They would like to repeat behavior that gives them positive feedback. 
Try to keep a positive to negative feedback ratio high 5:1 perhaps. So look for reasons to praise the child. Saying, yes, yes goes farther than no, no. This means you have be on the lookout for positive behavior - it's so much more difficult to spot!
At the same time there are some dangerous situations where you simply have to take immediate action, for example if the child is about to reach out to the sharp edge of a knife, or touch a hot iron or put his fingers in the electric socket. Attempt to keep the home child safe by removing access to these scenarios and if they do occur the first task of the parent should be to remove the child from that situation, it can be included with a loud voice and a loud no. This acclimatises the child to stop doing whatever they are doing (like trying to cross a road without assitance) when they hear you shout in the future.
Let them get away with as much as they can. It's the discovery phase after all. Involve them in tidying up once they make a mess, so putting things back in their places becomes an interesting activity.

Both shouting in your baby's face and hitting her in the mouth seem very wrong to me. 
At one year of age, your baby will understand from the tone of your voice that you mean No when you say No. A good way to deliver the message is to say No and then provide a reason why your baby should not be doing the thing he/she is doing. This way you are not simply providing arbitrary boundaries, but logical ones --- and your baby will be able to understand the reasons, eventually.
We use more than just No. We have a kind of playful warning "Ej ej" (Swedish) for something our girl shouldn't be doing, and a very clear "Ouch" if she's going to do something that will hurt, such as touching the heater. At other times we lift her out of the situation, saying No and explaining why. If she does something that hurts one of us, such as pulling our hair, we give her the cold shoulder for a little while, to let her know that that is not a nice way of being affectionate. 
Our little girl is getting the message, and often repeats back the message to us (well, just the single word). It does not restrict her curiosity and certainly takes more than one try to get the message across, but it does not involve any shouting or hitting.

First of all...
GO YOU
for listening to the part of you that said something was 'wrong' with your style. I wouldn't personally call it 'wrong' so much as ill advised. But you heard that voice. So many parents either can't hear it or ignore it.
So... 
Reminder: She's 1.
That means they cry when something scares or hurts them. The fact is that then you scream in her face (did you mean Scream scream? or merely Speak Loudly?) and she cries, it's because you scared her.
At 1, there's not a whole lot they can comprehend. But most babies that ages know the word "No" second only to knowing their name. Take advantage of that. I'll bet that you could say her name, then "No" and get a reaction. Read her actions... she may step back, look at you, things like that. At some point you may have to physically remove her from the situation, but truly, you can do the whole thing and get the exact same reactions from her (meaning she'll be right back at it in :05) by using even tones.
Hand "spanking" is really all about getting their attention. You don't have to do much more than golf-clap the back of their hand to snap them to reality long enough to point and say "No." (If you're doing it harder than that, you're just wasting spirit) Even that, however, isn't really necessary or effective with a 1 yr old. They don't really get it. Save the contact for a kid that can understand the explanation that should come with it.

"Dude >clap< No. Peanut butter sandwiches don't go in the vcr. Put it on your plate where it goes.
