I wouldn't use nails .... bad holding power, splits wood & looks ugly!
Depending on how high your canopy is, you might want to use 1x3's for your frame. <I used solid 1x8" for my sides, then joining that with 1x across the front & back. At the back, I use 2 1x3's, one at the top & one at the bottom, leaving a good sized gap all the way across for ventilation. My front is tapered, so a single 1x joins the front.>
For joinery, I used glued rabbeted joints. reinforced with screws. The rabbeted joints keep the canopy square & prevents shifting. For the top, I simply inset a 1/2" plywood into the frame. I rabbeted the top edges of the frame so the plywood edge is covered with solid wood. The plywood is more stable than solid wood, so when glued into the frame, keeps it flat.
1x's can cup & bow when exposed to moisture, esp. when you don't get furniture grade wood. So it is important to design your joinery to minimize it. I would not use a single piece as a flap door. <You need to use frame & panel construction if you want a flat wood door.> I cheated & use acrylic instead. Also, I use "5/4" stock (1.25" thick nominal, usu. 1-1 1/8" after dressing), this is more stable than the usual 3/4" 1x stuff.
