Hello,

Let's say I have two frequency response curves, one for Magnitude and another for Phase, which represent the desired EQ. The frequency response is in the form of (bin #, value). For example, the Magnitude response is of the form (bin 100, +12dB) for each fft bin. Likewise, Phase response would be of the form (bin 100, -90 degrees).

How do I generate the FIR filter coefficients?

Most would use software like e.g. rePhase. You don't just look at the amplitude and phase at a single frequency when designing filters.
