I am a union bricklayer in Pittsburgh PA and we encounter this daily. In order to accomplish this correctly, you must first determine the width of the beam. The bearing plate should be roughly 1.5 times the width of the beam with two "finger" welded to the underside of the plate. There should be a minimum of 3" between the fingers. And the fingers should be at least 5" long. The block wall should have vertical rebar reinforcement (#4 rebar min.) extending from the footing to 6" below the bearing plate. This cell should be fully grouted. Your mason should understand the specs. If this cell is not grouted and reinforced, the wall will crack and fail.
