A Level 85 Lucario will have to be taught Aura Sphere by the Move Re-learner. The Move Re-learner can be found in Mistralton City in the house by the Pokémon Center in Pokémon Black and White whereas she can be found in the Pokémon World Tournament building in Pokémon Black 2 and White 2.
You'd have to take it to the Move family house in Mystaltron, and pay with a Heart Scale to allow it to relearn old moves. (It can relearn a move it never actually knew, all the relearner does is let it access all level-based moves of a lower level than it is now).
