There is no easy way of using IRF9630s to drive common anode LED strips. Here are two suggestions.
The left-hand one uses PNP darlingtons, which will drop around 2V. So you will need a 14V power supply and small heatsinks for the darlingtons. You can probably omit the 1K resistor, because the darlingtons have 8K resistors built in to them.
The right-hand one uses an octal inverter chip to feed logic level mosfets. There are lots of variations on this (for example, using transistors instead of the 74HC240), however the main thing is that you need to invert the signal polarity between the TLC outputs and the mosfets gates, otherwise the PWN will work in reverse and you won't be able to turn the LED strips complete off.
