The Eagles manager had seen his side lose their last four matches but they were inspired by Everton loanee Vaughan on his home debut and ran out 4-1 winners.
"James was excellent," said Burley. "I feel he will do very well for us, he's a very good striker, young, hungry and has a lot of good attributes.
"It doesn't get much better than a hat-trick on your home debut so he'll be very pleased."
Vaughan opened his account in some style, latching onto Owen Garvan's square pass, turning in a flash and smashing the ball high into the net.
"His first goal was a great finish, he had his back to goal and swivelled and hit it into the top corner," added Burley.
"When you watch him in training he has that quality so you want him in the box."
