Do a search on battery draining or something similar to get some more ideas, but I would start with checking the easy things first.

If you have a meter than checking the amps and removing fuses as norske mentioned is a good first start.

Things that you can disconnect for test purposes are any aftermarket components, like radio, cd player, amp, etc.

The alternator and/or voltage regulator can cause battery drain also. If you have the external regulator, disconnect it and the alternator. If it's the new style internally regulator, the diodes can cause voltage drain so disconnect it also.

Check for bad cables and connections.
