I don't think there is per se...but the various race writers that came I pointed at the Freespacer and Sourcian pages, as those were the only two major races to be passed since the race ban so should be excellent examples of what sort of stuff a page needs. Though do keep in mind when they were actually approved they had a lot less detail than they do now; over time they became polished and deeper, so to speak.
I always thought the lack of a proper template was to prevent the idea of writing a species from getting into new players' heads, or into the head of anyone not serious really. The entire point of the race ban was to drastically cut down the number of parallel races, so anything that would reduce the publicity of the ability to write races might be encouraged -- At least, I think. I remember some commenting on the whole "too crowded" issue (and draining the player base) when the original race ban was submitted...anyways, I forgot where I was going with this. ^_^;
But yeah, just glance over at the Freespacer or Sourcian pages.
