Clay is not "bad" soil, it often contains loads of useful minerals and will hold nutrients well once it's broken up. Normal advice is to plough in many tons of manure, not so practical in the average garden though. You could double dig and manure it, or for a less physical approach plant loads of comfrey on it. Comfrey sends down very deep roots, even through clay, it drags up useful minerals to the surface, and if you dig it in the rotting roots will leave useful drainage channels into the clay. "Bocking 14" is a good variety, it's sterile so won't take over your garden, easily propagated form root cuttings.
