I would stick to whole grains/ root vegetables for carbs. Whole grain pasta or homemade sweet potato fries are a good option.
Follow the advice of plant based bodybuilders during their "bulking" phase.
Since you aren't vegan, then dairy would also be an option.
LOL I did this when I needed to gain a lot of weight to get healthy as a vegan. I read "Vegan Bodybuilding and Fitness" by Robert Cheeke. Sometimes I had to eat upwards of 3000-4000 calories to gain weight (which is like regular to light consumption for him). I am a 40 something year old post surgically menopausal woman with hypothyroidism, so weight gain isn't that hard for me, but I am also active and sort of a health nut as far as what I eat. And still somewhat cautious.
I'm not too big on tons of high fat foods, even in my weight gain phase, because my body can't physically handle a lot of high fat food without becoming ill. I did consume a few servings each day of peanut butter, or almonds, or stuff like homemade avocado basil pesto on pasta.
I also made homemade whole wheat bread and added stuff like flaxmeal, sesame seeds, and molasses to it to make it a little richer. Then enjoyed sandwiches like hummus/red pepper/sprouts, or peanut butter and banana sandwiches. Or tempeh and sauerkraut sandwiches.
I also drank full fat plant milks or higher calorie ones like full fat soy milk, full fat almond milk, hemp milk (even the unsweetened is higher calorie), rice milk.
And I ate, and still eat, four meals a day evenly spaced out. In my full on weight gain phase I ate six meals a day because I could not eat a ton of food all at once. Some "meals" were snacks like an energy bar and a class of soy milk.
Also, raw grains like oat groats or buckwheat groats can be soaked overnight and eaten as is with dried fruit and seeds added. A cup of raw grain would be double the calories as a cup of cooked grain, and more nutrient dense because the water content is lower and food content higher. And it is not too filling with a lower water content. The same goes with pureeing beans and making a dip and having that over rice, or pasta, or in a sandwich as opposed to the whole bean. White bean garlic dip is one of my favorites!
For fruits, choose more dense ones like bananas, pineapple, pears.
And don't forget to enjoy a plant based dessert on occasion.
