There's a great thread on the soapmakingforum.com that goes on for about 16 pages on shaving soap. The classic wet shaving bar has lots of stearic heavy oils (like tallow) or uses stearic and/or palm.The best bars seem to be soft or semi-soft, and use either only potassium hydroxide, or a mix of potassium and sodium hydroxides. It's a really great read if you're trying to make a good shaving soap, and the participants were very generous with their experience and experiments.
The basic recipe (with many variations) was about 50/50 stearic acid/coconut oil hot processed with potassium hydroxide (not sodium) which is them smooshed into bowls for use. You can play with the proportions, split the hydroxides, add clay, add glycerine, add butters, use some sodium to make a harder bar that can be cut, and so on.
If all that is more work than you want, I hear Bramble Berry sells a very nice melt and pour shaving base, to which you could add clay, or colloidal oatmeal, or whatever.
Hope that helps!
