Frankly, I can't think of anything really important in terms of rules changes on the DM side.
Adventure design plays into "AD&D feel" a lot. I noticed in Out of the Abyss that the trend in 5E seems to be having lots of bite-sized encounters and lots of opportunities for short rests between them. For an AD&D-style adventure I would make the encounter areas much larger and more dangerous, so that the players are forced to choose between retreating (and giving the monsters time to regroup and set traps) or pressing on without a short rest.
