For plants you'll need very robust and well-rooted plants (maybe best to keep them in pots) since Oscars are notorious for re-arranging on a regular basis. Good potted plants would be very large crypts, swords, arrowleaf, or other very large plant.

You could also tied some epiphytes like anubias or java fern to some large driftwood that the Oscar can't push over easily.
