Is there a general equation which will give you an approximate relation between the age of the universe (t), and it's temperature (T) at any time [t]?

The temperature can be related to expansion

but the exact relation between expansion and time depends on incompletely understood effects of inflation and dark energy.

That's the time that we can't see because of Thompson scattering in the plasma, athough we can get some clues from the anisotropy in the CMB.
