Water and Ethanol Vapor Phase diagram for specific range
The Dortmund Data Bank might be a resource to start searching.

They do seem to have a page for vapour-liquid equilibrium data for the ethanol/water mixture. 

On a first view, however, the data seem to be for less than atmospheric pressures only and are compiled from Ind. Eng. Chem., 1942, 34, 1501–1504.
