I usually try to write as if the actions are happening in the now. Present tense I guess. I avoid accusations of godmodding by giving clear indication of my character's intent as well as leaving the result open for the other person to put in.
For example: "Cecilia makes a tackle at (insert character name here)'s legs in an attempt to trip them up." This leaves it open for the other player to decide if my character succeeds in her attempt.
