First thing that you need is a know-how of CAD tools like EAGLE.
Have you designed a circuit before?

You can find reference designs to start your Arduino Shield design by following the below links:
SparkFun EAGLE Library
This repository contains several EAGLE Libraries. The Boards library contains a template for Arduino Uno R3 Shield layout.

You can start experimenting from there. We also have several Circuit design files available at: Explore Labs GitHub
