This is my first time converting a recipe from all-grain to extract/steep, so let me know if things seem off at all. The IBU's and color are a a bit high relative to the OP's AG recipe. Also I left out the Munich malt and flaked oats since they need to be mashed. I suppose you could add a bit of Munich LME to make up for it, but the amount is nearly negligible (9oz). Anyways, here's what I came up with in ProMash:
