You can use the digital I/O pins for the I2C bus. The SDA pin needs to be birectional so you will probably have to use a hole 8-bit group just for this signal.

There are several ways to implement an I2C bus, with a hardware controller (there is one on Opencores) or by software using bit banging. Do you have a CPU in your project? What is it, if it isn't a NIOS?
