Preheat your oven to 400°F and line a baking sheet with parchment paper.
Peel and slice the carrots and parsnips into 1-inch chunks, then toss with olive oil, sea salt, and black pepper.
Spread the vegetables on the baking sheet and roast for 20-25 minutes until they are tender and caramelized.
While vegetables roast, steam the tempeh block for 10 minutes to soften the texture, then cut into 1/2-inch thick strips.
In a small bowl, whisk together the tamari, maple syrup, and garlic powder to create the glaze.
Heat a non-stick skillet over medium-high heat and sear the tempeh strips for 3 minutes per side until golden brown.
Pour the glaze into the skillet, tossing the tempeh constantly for 1 minute until the sauce becomes thick and sticky.
Plate the roasted root vegetables, top with the glazed tempeh, and garnish with hemp seeds.
