Hi Ted, I used to have a book which suggested several modulation patterns from any key to any other key. I loaned it to someone many years ago and never saw it again. I seem to remember it was just called 'Modulations'.
I've had a surf around some web sites and found the following which may be of interest to you. http://www.keyboardedu.com/pamphlet.html this is a pamphlet which costs $7 and is called 'Musical modulations' - sounds about right
There is another likely web site : www.themodex.com/info.htm which I found on Google and has an entry 'THE MODEX - seventy-seven modulations for bridging music'. Unfortunately, the site seems to be down at present - maybe have a look later
Hope this helps.....
