Smoking brisket for Father's Day - recipe advice?

My kids want to do something special for Father's Day and somehow agreed to let me smoke a brisket. I've done ribs before but never a full brisket. I've got a Traeger and like 8 hours. What temperature, what seasonings, how long does it actually take? Want to impress everyone but also not mess this up because it's like 60 dollars of beef.
