Found an interesting brief on the ASTB on the web made by one of the PhDs at NAMI. Goes back to '04, but the info relates to the current tests:

Slide 15 goes into more detail on the mechanical. Here's the division of items in the mechanical test bank for those who don't want to dig through the Powerpoint:
17% Electricity
1% Frequency/Wavelength
16% Force
5% Pulleys
5% Rotation and Revolution
11% Weight and Balance
5% Fluid and Air Flow
11% System Components
2% Volume and Area
11% Direction and Vector
5% Temperature and Properties
4% Energy and Power
7% Other
I think these percentages are the entire test bank for forms 3, 4, and 5 combined, but I think it gives better info on what subjects to cover than the books.
