Transtopia

Probably the best religion I would have to say. Pretty much a union of anarchist and transhumanist ideals. Their manifesto sets out in detail their principles by which to follow. It used to be much more detailed, but for some reason they cut a lot of it out and made it simpler.

Excerpt:

General goal: infinite existence under optimal conditions
Primary means: reason, science, and technology
Motivation: enlightened self-interest

Yep, sounds pretty good to me.
