You COULD get clever with the hall sensors, they'll tell you which way round each coil should be at any instant of rotation. Feed the hall signals to a bank of nice low on resistance mosfets, and make the mosfets switch like diodes - it'll be MUCH more efficient for a low voltage motor, since you won't be wasting 0.7 x output current Watts.

How many wires do you have ? I'd guess you have a polyphase AC coming out - an AC signal off each winding of the motor. Find the common wire, and wire a diode's anode  off each coil. The cathode of all the diodes is the output.
