I think a good way to go about it is to look at how much you eat now. Add 200 cal/day to that for starters, unless you're eating ridiculously tiny amounts. If you start seeing progress after a couple of weeks, great. Stay there. If not, add another 200 cal/day and repeat the process. Once you start seeing progress and then stall for 10 days or so, add 100 cal/day, which is then your default jump.
You're weighing in around 172 lbs, so your maintenance window is 2400-2900 cal/day. Adding 900 cal/day to the top end of that is kind of excessive, and I think you'd probably gain a bunch of fat - which isn't exactly optimal. At six feet and 172 lbs you're pretty skinny, right? So you're not carrying a ton of muscle. Chuck in a sudden, large calorie surplus and your body is likely not going to know what to do with it and end up storing any extras as fat. Be patient. Find the smallest possible surplus that will give you muscle gains and milk the hell out of it.
In terms of macros, definitely up your protein to 200 g, and I'd say shoot for 35% of daily calories from fat. The rest is carbs. Any time you add calories, add them in carbs leaving protein and fat the same. The reasoning is that you're adding calories because you stalled, which means you've added muscle so your body will be a little better at using carbs than before.
