Carp for a 7 Year Old - Help!

I am taking my 7 yr old nephew fishing in a kid's tournament.
He has only been fishing twice before. I asked him if he wanted to
 catch a lot of fish or did he want to win the tourney with that 1 big
fish? 
He wants the big boy :-)
It is an aggregate weight tournament, any species allowed, fished in a
small lake.
We are going for carp. I am a salt water fisherman. 
I have done some freshwater fishing and can remember that 3' carp I
caught accidentally, 40 yrs ago on my Zebco 202.
I would like my nephew to have a similar memory!!!!!!!
I am going to let him use my 15 lb Ugly Stick spin outfit.
What is the best line, hooks, weight or rigs to use for this and what
bait is most productive.
Thanks for any help in creating a lifetime memory for a 7 Yr old!
