I went through the process for AP English Literature and Composition. It's a little time-consuming, but not that hard. There's lots of good information and actually four sample syllabi on the College Board AP website:

I also googled "AP Literature Audit" and "AP Literature Syllabus" and found many that teachers have posted online. This was helpful, as well.
The first time I sent mine in, they sent it back with a request to add one minor aspect (I don't even remember what it was it was so trivial.) I added what they wanted, sent it back, and had approval within a few hours.
Thankfully, once you have a syllabus approved, you only have to resubmit the same syllabus each year, even if you change the syllabus.
If you have further questions, I'd be happy to help!
