Nick Fury's not as integral to the plot of Age of Ultron as he was to the first Avengers. When we first see him, in fact, dude is hanging out in the shadows of Hawkeye's old barn, with only a broken tractor for company. It's not exactly the super-slick S.H.I.E.L.D. headquarters he's used to. Still, the dust and haybales don't seem to bother him. Fury starts dispensing advice to the broken team almost immediately:
Nick Fury: Here we all are, back on Earth, with nothing but our wit and our will to save the world. Ultron says the Avengers are the only thing between him and his mission. Whether or not he admits it, his mission is global destruction, all this laid in a grave. So stand. Outwit the platinum bastard.
Funnily enough, the pep talk works. The Avengers figure out Ultron's next move, come up with a plan of action, then head out again to take the cyber-baddie down.
Fury's not quite done being a Helpy Helperton, though. Just as the Avengers are resigned to the fact that they'll have to blow up floating Sokovia with everyone still on it, Fury pops out of the clouds with a Helicarrier, ready to airlift all the citizens to safety. He's saved the day again. Wisdom, ingenuity, and great timing—Fury's got it all going on.
