Nah, you just need to have a board with one piece on it and generate all possible moves for that piece from that postion. Then put that data in the lookup table and do it again for the next piece or position. You'll still have to do a little runtime work like check that the piece isn't jumping over other pieces (except for knights) and isn't landing on a square already occupied by a freindly piece, plus few other special cases (like pawn attacks). For the most part, though, lookup tables get the hard part done.
