Make the level generation process two-step.  Step 1, build the map.
Step 2, populate it with items and monsters.  When the level is left,
save the state and positions of the items and monsters in it along
with the seed.  When re-entering a level, do only step 1 of the
process, and then repopulate it with the saved items and monsters.

Of course, if you ever want to introduce features that can actually
modify the map, then you'll need to save and reload the modifications as
well.
