It's likely an 11/32" square drive. Snap On and others sell them (shown below), or you can make one from a 1/2" drive to 3/8" drive adapter by grinding the 3/8" end down to fit the pipe plug.
I've always used a torch to heat the cast iron around the plug before removing, but you might
get yours out w/o heat.
