Are you trying to re-emulsify the dye throghout the clay, or are you trying to get it to the surface of the clay? Either way, I believe your best bet is to gently soften the clay, then once soft, mix it around with your hands. As I said before, use nitrile gloves - they're cheap and nontoxic, and they also don't hold a stain, which should include the dyes within the clay. The downside is a loss of tactile sensation, but when the clay is properly mixed you may be able to ditch the nitrile.
Again, you may already have thought about this, and think this is stupid advice, but given what I have for a basis (zero knowledge of artist's clay) this is the best I can do.
I'm officially AWOL on this topic, as of right now. (And I mean it.
