Make a fine powder that easily sticks to the chips by grinding the spice blend in a coffee grinder, spice grinder, or high powered blender.
Fill a plastic bag or a large glass jar with the spice blend and the tortilla chips, and shake until the chips are fully coated with the spice blend. If your chips don't all fit in the bag or jar, work in smaller batches until you have coated all of the tortilla chips. I didn't have any problems coating the chips because of the fat content in the flaxseeds, but you can spritz them with a tiny bit of oil to get the coating to stick better if needed.
Remove the chips from the bag or jar and serve immediately, or store them in a well sealed container until you are ready to eat them.
