BF estimates are difficult. If I had to guess, I would say 14-15%ish. You don't have much fat, but you don't have a ton of muscle either.
The best way to approach a lean bulk is to understand that building real muscle takes years. Strap in for the long haul and be consistent. Find out your caloric maintenance level and each just slightly above that. (250 kcal surplus).
I personally like my calories from my macros evenly split, 33%kcal protein, 33%kcal carbs, 33%kcal fat. I'm certain you already know that protein and carbs have 4 kcal/gram and fat has 9kcal/gram.
Get on a program that has you working in all rep ranges heavy compound lifts with lower reps and isolation lifts with moderate/high reps. There are plenty to choose from on this site.
Don't forget about your legs either.
