The simple thing is to write everything as a system of ordinary differential 

 dE/dV + dE/dT DdT/dV = - P 

consider now the unknown function T depending on the variable V , with the 
initial point T(Vi) = Ti and integrate evrything in the interval (Vi,Vf) 
using NDSolve. 

I do not have mathematica at the moment but you should write something of the

 NDSolve[  dE/dV + dE/dT T'[V] = -P , T[V] , {V,Vi,Vf} ]
