You have to be more specific as to what you are compensating for. If it's field of view, then do as Pavel recommended. If it's DOF, use a CoC compensated calculator like
this one. If its "magnification" remember that the crop factor only "magnifies" when printing like sized prints. Subjects in the viewfinder are not closer on your 30D than with a film camera, using the same lens. A 50mm is still a 50, and provides normal, or no magnification. But, and it's a big but, the field of view is noticeably smaller on a 30D, so much so that something like a 30 or 35mm lens will probably get you that "50mm feel." Personally, I don't get my head involved in the confusion of cropped sensors and their 35mm equivilent, sticking to figuring out what focal length will give me the FOV and working distance I need to take the shot.
