I made this breakout for the OV9650 a while ago, and I've been waiting to test it before sharing, I finally had the chance to do so, I used an FPGA this time for testing, and here's the result:
The breakout has two SOT23 LDOs for the sensor's core, digital and analog supplies and requires a single external 3.3v supply, note that most sensors have internal regulators for the core supply, so technically you only need one, anyway, those LDOs should be fairly easy to source, their exact voltages depend on the sensor used. The board is compatible with a few other Omnivision sensors, such as the OV9655, OV7660, OV2640 etc... however, make sure it has the same pinout...

Alternatively, you could order the PCB directly from OSHPark:
