Apply the following modifiers to the base creature and then add class levels as appropriate.
+4, +4, +2, +2, -2
If it's a base 0 hit die monster (drow for example) then your base stat array would be 11, 11, 11, 10, 10, 10 followed by racial modifiers and the above elite stat array (you can mix and match the 11' and 10' however you choose).
I for one love making monsters with class levels. Have fun!
