What practices are included in (daily lay) life for a Buddhist? There are a number of Buddhist traditions, each with different teachings and practices. What are the daily practices lay people normally live by? 

For instance, living by five or eight precepts, in the Theravada tradition, or just daily meditation practice. 

How do the different Buddhist traditions compare, in terms of daily practices? What is common among different traditions, and what varies?

Revised question Since many people ask about choosing a tradition on Buddhism.SE, the purpose of this question is to gain clarity about the differences (and similarities) between the traditions. There appears to be a clinging to the known tradition(s) among many, and rejection of other traditions (as good or bad)

Here are a few examples. I am looking for some more insightful comments from those experienced with more than one tradition, since these are merely what Google provided:

Bhikkhu Kantipalo (1995) from the Theravada tradition:

Found this about Zen practice on zenki.com (unsure of the authority, since I'm unfamiliar with Zen)
Yes, it is the five precepts on normal days and 8 precepts on Poya days. Apart from that, do meditation and good deeds whenever there's an opportunity. Or simply come up with plans to avail opportunities to do good deeds. Just like how we normally plan or devise ways to gain sensual pleasures.
