Dom wants to switch

My Dom has expressed his need for me to take a more dominant role as it is something he misses. As a sub clearly I want to make Daddy very happy.

While there are ways I can imagine myself using him, I am very much into taking orders and pleasing. In this case, I don't know where to begin or get into the right mindset, and overall the task seems daunting. Any experience and/or advice would be lovely.
