Not having read all of LaVey's books I'm not entirely sure what you're after. I can make an informed guess though and assume you're looking for the enochian alphabet.
Try this website:
www.omniglot.com/writing/enochian.htm
The Enochian alphabet was originally transcribed by John Dee in the 16th Century via the scrying of Edward Kelly. It is the language of the angels.
That site has a few other alphabet systems that may also be helpful to you if that wan't what you were looking for.
