Under the object editor, there is a field called bounty. Set this to 100 gold and 100 lumber.
From there, you can go to the trigger editor. Make a new trigger that has the event "Map Inizilization". Then create 8 actions. These are PLAYER actions. Under "Player Flag On/Off", enable it for all your players.
You could also create a trigger, that has the event "When a unit dies". From there, Use another player action, and use "Add Property". Add 100 gold to "Owner of Unit > Killing Unit". Do the same for lumber.
As a not for the future, but more time into your posts if you want to recieve help.
