Here I was, way past midnight, face to face with a situation that could very well become an incident of prejudice and chauvinism caused by the unjust policy of our society today.

here i was为表语前置，here为表语。way past midnight为时间状语，face to face with...为副词+介词构成的副词短语。face to face为副词性习语，再被with介词短语后置修饰，作伴随状语。
