I have a function of the form

> Exp[x] Sin[y] = K;
> 
> How do I plot this function for different values of K?
> 

Use
     Solve[ Exp[x] Sin[y] == K, x ],

(or solve for y), then assign the result to a function and use Plot3D. 
Note that the domain giving real solutions is restricted, though.

You could also use
     ImplicitPlot[ Exp[x] Sin[y] == someNumericvalue, {x or y, startV,
          stopV} ]
