Narrative:

I had flown from pao to ZZZ to pick up some parts for work. I received a standard briefing via duats before departure; which showed clear weather and one tfr over oakland which was well off my route. On the return flight; the weather was the same and I didn't obtain another briefing. Approaching livermore (lvk); I noticed a plume of smoke from a wildfire in the hills near livermore. Though neither my xm weather nor my ads-B weather showed a tfr; I realized one may have just popped up and I turned to remain clear.the combination of a recent briefing; the clear weather; and two independent sources of downlinked weather/tfr information led to a sense of complacency about tfrs. Corrective actions include getting flight following as well as always getting a briefing.
