Again, up to the GM, but you're sprouting Wings, a Tail, Armored Scales, and putting on some undefined amount of mass. If these changes can be accommodated I'm not sure why Man to Wolf or Troll to Bear would be so incredibly different. YMMV though.
All right, I'll lay it out with a simple example. Take urban explorer gear, which is basically an armored jumpsuit. You really just need some expansion zones to cover the increased mass (including scales) and holes in the back that the wings and tail poke through when you grow them. The arrangement of the head, arms, legs, and so on are the same, you're just making it so that things poke through and expand. But that isn't what's happening when you go from Human to Wolf, for instance. The tail isn't a problem, and changing size to go smaller is only a moderate problem (it is easier to have flaps that expand than to automatically 'take in' flaps to go smaller). The problem is the arrangement of limbs. The positioning of the head and legs is very different on a a wolf than it is on a human.
The same is true for, say, the Lined Coat. Converting this for a Drake is even easier than the Urban Explorer gear. Just have to make sure it is either big enough to fit the new form, or can expand, and have the holes in the back for the wings. A split back, like you often see on trench coats and dusters to allow ease of movement will allow the tail through just fine. Done and done. But when you try and do that for a quadruped, the coat is going to be dragging the ground in all kinds of places, and you STILL haven't solved the issues caused by the different arrangement of limbs.
And then you have the issues of getting the protection in the right place, as I mentioned before. A human and a Western Drake both walk upright, have two arms, and two legs. The majority of their vitals are in their torso, and that is why most armor concentrates on the front and back of the torso. On a quadruped, the front and back of the torso are largely concealed, unless you're attacking from above or below, and the sides are more exposed. This means most armor for, say, concentrates on the sides of the body, rather than the chest and back. You can't just take a bulletproof vest designed for a human, and cut it down to dog size. Everything is different.
The only way you could solve all these problems is with high tech nano-materials, like with the Smart Blades. But absolutely no one is doing stuff like that right now thanks to the nanopocalypse.
So your best bet would be something like a helmet or ballistic mask that has straps which will allow it to stay on when you change, and then having your team help you into your wolf armor. Or use magic armor, either through spells or being an adept, since those would carry over in your other form.
