The quick answer is to use a product like Hardies compressed sheet on the decking but lets see what others think.
I nailed batten of different thickness underneath the deck and then screwed corrugated plastic sheeting to them. This provided sufficient slope for water run of.
You could use corrigated iron or similar. Screw through the top corregation and not the bottom one.
