Simplistically:

1) Configure the Audio CODEC via I2C

2) Buffer the incoming ADC data samples in the FPGA

3) Write the data to the SD card via an SPI interface.

I suspect that may not offer you all the answers you're hoping for. For that (in this forum at least) you need to ask questions that are more targeted, with details as to what it is you're hoping to do...
