I'm a plot first, let the theme emerge kind of writer. Partly from time as a journalist, so I tend to look for the angle, the unique thing that will motivate me to write a story. Partly from a horror of didactic, message-of-the-week writing.
Establishing the thematic architecture is crucial for adding depth to a narrative, and making sure the different elements contribute to that architecture. But for me, it's plot before theme every time.
