Steam the carrots: Peel the carrots into long ribbons (think smoked salmon-style strips).
Steam over boiling water for 2–4 minutes, until just slightly tender. They should be flexible and silky.
Make the marinade: In a small bowl or jar, mix olive oil, soy sauce, rice vinegar, smoked paprika, garlic powder, kelp powder and optional capers and maple syrup.
Taste and adjust flavour—add salt as needed.
Combine: Gently place the steamed carrots in a shallow container. Pour the marinade over, making sure all the ribbons are coated.
Cover and set refrigerate for 20 minutes or overnight to develop flavor.
Serve: Enjoy your carrot lox on toasted bagels with vegan cream cheese, red onion, capers, and fresh dill—or in wraps, salad bowls or sushi.
