I've been working in a clinical research position at a hospital. I know some people who work in basic science labs or as ER scribes. If money isn't an issue you can also spend the year getting clinical experience through volunteering, though I believe some med schools want to see you being employed for at least some period of time.
Working as a clinical research coordinator and volunteering with Habitat on weekends. I have friends applying this cycle who are working as a scribe, doing a post-bac research internship, and getting an MPH.
