I've had an ongoing email conversation with Paul, who is a newbie to university teaching in Korea. Here is an excerpt from one of his emails:
"At my uni I've been completely left to my own devices and whichever curriculum I develop is completely up to me. Having no supervision is great in many ways but also a little unsettling in others for a newbie."
Remembering back to own situation 4 years ago, I understand exactly how he feels. Some thoughts on how to handle this:
1. Talk to your coworkers who've taught at the uni for a while. Everyone likes being the "expert" and I'm sure they won't mind answering your questions (just like I don't mind answering reader questions). If you don't have a shared teacher's office, and rarely see your coworkers send out a group email with your questions and I'm sure you'll at least get a few responses.
2. Relax. Administration at unis in Korea generally have low expectations. Just show up to class every week, give some tests, input attendance and final grades, come to meetings, and don't sleep with the students. Really. Now, of course as a professional teacher your own expectations for yourself should be much higher but don't stress about curriculum and stuff. No one else is.
3. Do some searches online for things like, "writing class university Korea syllabus" or "freshman English university Korea." You'll find that many teachers post their syllabi online and this can be a valuable resource for you.
4. Read the archives of this blog for some more tips.
5. Ask questions on the Korean Job forums at Eslcafe. Many uni teachers are on there and will answer any question you have.
