We got a lot of great compliments on our wedding ceremony, especially from friends who, like us, aren't really religious. In answer to the questions we got, it was cobbled together from other ceremonies we found on the internet, and we added our own touches where we thought it was appropriate. We were really happy with how it turned out.
So that others can do the same thing, I posted the ceremony on our wedding site. Take what you want, or use the whole thing, if you're so inclined.
