In a small sauté pan, crumble the tempeh and add enough water to almost cover. Over high heat, steam the tempeh until most of the water is absorbed, about 15 minutes.
Drain any remaining water. Add the fennel seed, basil, marjoram, red pepper flakes, sage, garlic, tamari, olive oil, and lemon juice. Cook over medium heat, stirring occasionally, until lightly browned, about 10 minutes. Add extra oil if needed.
Use immediately or store in the fridge for up to 5 days.
