Theoretically the temperature dependence of the energy bandgap can be determined from the following equation:
Eg(T)=Eg(0)-[(aT^2)/(T+B)]
Where a (eV/K) and B (K) are fitting parameters. Eg(0), a and B are all unique to every single material including the doped systems, I think you can find a data base having those parameters from experimental physics journals.

Temperature dependence of band gap is not same for various semiconductor materials. But you can by using a simulation code measure value of band gap at different temperatures. Then you can find a function for variation of band gap versus temperature.
