One approach might be this:
Weigh and write down everything you eat - grams of protein, carbs, and fat - for 7-10 days.
Weigh yourself at the beginning and end of the 7-10 day period.
If your weight at the end of the 7-10 days has stayed within 1-2 lbs of what you weighed at the beginning of the 7-10 days, you'll know what maintainance caloric intake is for you.
Now, you can add 300-500 calories per day to this. Yuo'll then have to monitor what happens. If you find your bodyfat increasing too quickly, you'll cut back a bit on the extra calories. In "bulking" (which I've never had much use for) you're going to gain a little bit of bodyfat, and "smooth out" a bit - this is ok. But, if you're natural, and gaining more than a pound or so a week, especially starting at 185, it highly unlikely that this gain is quality muscle.
Try for 1 1/2 grams of protein per pound of bodyweight (maybe as high as 2 grams per pound if using AAS), keep the fats low and use things like Flaxseed oil for most of it, the rest can be carbs, but try to stay with low-glycemic carbs rather than simple.
You'll have to adjust and fine-tune as you go.
