How do I become a Buddha, the stages of the path? I'm interested to see the process broken down into steps preferably using Theravada theory, all in the context of a summarized "how to".  

This would range from trying meditation, through all the stages of insight, enlightenment, into and through any other stages, and into Buddhahood, assumably hundreds or more lifetimes from now. What are the stages?
The Buddhist path is the Noble 8 Fold Path which is divided into


Morality
Mastery over the mind
Wisdom


(Three fold training.)

You should start by leading a moral life, develop mastery over out mind without being a slave to it, then practice Vipassana gain Wisdom. This intern helps you strengthen you morality and so on and so forth.

In addition you have to practice the Perfections to become Enlightened.

Practicing the Perfections and walk on the Noble 8 Fold Path you will slowly but surely progress towards enlightenment. If you want to be a Buddha the Perfections you have to full fill are greater. Also in practicing Wisdom you have to stop before you reach the 1st stage of sainthood.

In addition you have to be ware of the Dependent Origination, Three Marks of Existence, 4 Noble Truths, Factors of Awakening, in order to make you pratice of developing wisdom fruitful and well directed.
