Preheat the oven to 300 degrees and line a baking sheet with parchment paper.
Add the melted butter, dry seasonings and soy sauce to a large mixing bowl and whisk to combine. Pour in the crackers & pretzels and gently toss until everything is evenly coated. Transfer the mixture to the baking sheet and spread in an even layer - if it seems overcrowded, you can spread them out on 2 baking sheets.
Place in the oven on the middle rack and bake for 20 minutes, flipping halfway. Remove from the oven and allow to come to room temperature. Serve immediately or store in an air-tight container up to 5 days.

Notes
You can switch up the type of crackers you use if you can't find the vegan cheese crackers - some other good options are Ritz or Saltines.
Be sure to keep an eye on the crackers after the first 10 minutes - you want them to brown, but not burn.
