Just now, in my hall bath, the light switches do not work. There are two parts to that bathroom, the vanity area, then in a second room, the toilet and shower area. Each have their own light and light switch. The outlets all work fine, just the light switches do not work. I have reset all of the circuit breakers and have rest all GFCI's in the house... the light swtiches still don't work. Any suggestions?

First pull switches and see they are wired using the quick connect holes in the rear. Using the quick connect method of wiring is know to develop poor connections over a period of time.
If that is not successful post back with a description of the wiring in the switches. Where to look next will depend on how switches are wired.
Do you have a mufti-meter?
