Where is your next buck? (Specifically, not conceptually. Describe his bedding area, his feeding area, and his travel routes.)
Why is the buck here? (What is it about this situation that attracted the buck in the first place?)
How do you encounter him in a way that is undetected?
What changes are you going to make to adapt to his routine?
Start with this before you spend time on tactics, technology or strategies.
Good Luck and Good Hunting,
