Converting Extra Exchange - What is the Best Plan?

I played this game recently, and to my shame - lost the position with an extra exchange. What is the best plan to convert the material advantage? Is it possible to formulate it up front?

White has a pure extra exchange, but the black pawn on e4 somewhat prevents the white rooks from getting activated, and converting the advantage unexpectedly proved a challenge. Coordinating the two white rooks while insisting on exchanging one of them must be the key to winning this position.
