Keep food simple, juice boxes or Capri Suns, finger foods (kids and adults love them) and cupcakes.
What does she like? If it's anything Disney check out Spoonful.com for ideas. I went there for our upcoming Jake and the Never Land party and found the treasure chest cake I'll bake, food ideas and crafts. They have printable coloring sheets of all sorts, you can have those and crayons available, maybe have little "prizes" for the three best coloring attempts. They have craft ideas there, too, the older ones might like making something. If she's not into Disney do a search for the characters or things she likes for party ideas, they're all over the internet. At 2 my guy loved Elmo so I found Elmo face cupcakes to make, people asked me where I bought them ;)
You don't need games, kids like to play. All ages like blowing bubbles, you can find them at Dollar Tree. Balloons make everything special, blow some up and have them where kids can toss and kick them. Play some music so the kids can dance. And gear the party to your daughter, she's the birthday child.
