Ideas for ham recipe for potluck?

The company potluck is coming up. I have to be at work at 9 and we eat at noon. I'm supposed to make the ham, but don't want to get up in the middle of the night to put it in the oven. I experimented with a "crock pot" ham recipe I foind online, but it turned out stringy like a pot roast and not solid like ham is from the oven. Do you think I could cut the ham into slices and bake it in the oven while I get ready for work? Surely it wouldn't take as long because it wouldn't be a "whole ham". Any ideas?
