Preheat oven to 325°F. Line a baking sheet with parchment or a silicon baking mat.
In a large mixing bowl, combine the tamari, maple syrup, liquid smoke, and salt. Add the coconut flakes and toss very well to coat. Spread onto the prepared pan in a single layer. Bake for 15–20 minutes, stirring occasionally.
Let cool, stirring occasionally while it cools.
Can be stored at room temperature in an airtight container.
