Here's how I did it for my map. The thing about this is you have to set the amounts in the data editor for each unit.

EVENT

Unit - Any Unit Dies

CONDITIONS (Owner of (Triggering unit)) == Computer

ACTIONS

General - If (Conditions) then do (Actions) else do (Actions)

If

(Killing player) == 1

Then

Variable - Set Vespene Points = (Vespene Points + (Vespene cost of (Unit type of (Triggering unit)))

Variable - Set Mineral Points = (Mineral Points + (Mineral cost of (Unit type of (Triggering unit)))

Player - Modify player (Killing player) Minerals: Add Mineral Points

Player - Modify player (Killing player) Vespene: Add Vespene Points

Else
