If you happen to have unit vectors of one coordinate system in terms of the other's coordinates, it's easy: the vectors are just the rows (or columns, depending on which direction you want to make the transformation) of the rotation matrix (in the obvious order). As a major application area for this math is spacecraft attitude control, I suggest you ask some rocket scientist to lend you a copy of Wertz (shouldn't be hard to find a rocket scientist in Huntsville :-).
