I've just finished (well, I'll likely tweak it from time to time, especially once play begins to keep things from getting stale) a personalized modification of the Mentzer dungeon wandering monster charts for my own game.
It all fits on a single (A4, watch out Americans) page, has encounters for my above ground ruins (Outer Works and Keep), as well as Dungeon levels 1-10, and separate sub-tables for human types (to get more monsters on the tables), dragons, and oddities (random magical effects, traps, etc.). It's also got a little sub-table for motivations for creatures (hunting, slaving, returning to lair, etc.) and NPC party strength (how beat up are they, how many spells and magic items have they exhausted)
