I'm not familiar with any works of fiction on the matter except for Carl Sagan's contact, and that's mainly because it's written by Sagan. I'm personally gonna have to take a look at some of these Pratchett books others are talking about. I've heard that "The Golden Compass" book series is supposedly anti-religion, but i'm just going on hearsay here.
Regarding non-fiction, I think Bertrand Russel's writings on religion and science, specifically his work "why I am not a christian" is fantastic. The recent non-fiction works from today's prominent atheists, such as Hitchens, Dawkins, Dennett and Harris are primarily anti-religion, but they have bits of "what would the world be like without religion" hypotheticals sprinkled throughout their work.
I've also heard that Ayn Rand was an outspoken atheist, but i don't know if she wrote on the subject (never read the fountainhead or atlas shrugged, etc.)

The cosmos is also within us. We're made of star stuff. We are a way for the cosmos to know itself - Carl Sagan
