Well, this year our kids' baskets were in storage (we moved recently) and we forgot to get them in time for Easter, so we improvised a bit. One thing led to another, and I ended up coming up with this very intricate scavenger hunt, whereby they would be led from one "gift" to another. With each little gift was an egg. On the outside of the egg, it gave them something they had to do before they could open the egg (draw a picture of a bunny, play Hot Cross Buns on the piano, make an Easter egg out of the play-doh they were receiving, plant a pumpkin/watermelon seed they were receiving, et cetera...), and inside the egg it would tell them where to go next (i.e., "Look in the mailbox," or "Look in your carseat," or "Look in the piano bench"). It got a bit out-of-hand...I hope they'll enjoy it and that it won't be entirely lost on them (they're only 2 and 4--but the 2-year-old's "tasks" are things like "do a somersault" or "make an easter egg out of play-doh." She can't play Hot Cross Buns on the piano, anyway
As for the eggs, my daughter has a severe egg allergy, so we went with plastic eggs (we also hid some sidewalk chalk eggs). It's not that she couldn't participate in dying eggs, but we would have probably just thrown them out, anyway, since she can't have them.
The eggs primarily contain Chuck E. Cheese tokens, because we're going out to visit my in-laws next weekend, and they had told us that they wanted to take the kids to Chuck E. Cheese while we're there. We got a coupon online for 100 tokens for $10, and another coupon for a large pizza with 4 drinks for $18.99, so we bought the tokens for $10 and split them up into the majority of the eggs, and then one egg contains the coupon and a 20-dollar bill--so whichever kid finds that egg can "treat" the other kid and his or her grandparents to Chuck E. Cheese.
