Perhaps you can try implementing ModularTenantEvents and in this service, import the recipes from a folder eg.

public override async Task ActivatingAsync()
{

using (FileStream fs = File.Open(pathToRecipeJson, FileMode.Open, FileAccess.Read))
using (StreamReader sr = new StreamReader(fs))
{
    string json = await sr.ReadToEndAsync();
    if (!json.IsJson(JOptions.Document))
    {
         _logger.LogError("Invalid Recipe JSON.");
    }
    string tempArchiveFolder = PathExtensions.Combine(Path.GetTempPath(), Path.GetRandomFileName());
    try
    {
        Directory.CreateDirectory(tempArchiveFolder);
        System.IO.File.WriteAllText(Path.Combine(tempArchiveFolder, "Recipe.json"), json);

        await _deploymentManager.ImportDeploymentPackageAsync(new PhysicalFileProvider(tempArchiveFolder));

    }
    catch (RecipeExecutionException e)
    {
        _logger.LogError(e, "Unable to import a recipe from JSON input.");

    }
}

@weirdyang's answer is correct if you want to execute a recipe literally when switching themes, i.e. any time you switch themes. If you only want to execute a recipe once, when initially enabling the theme, then you can use the simpler recipe migrations approach: https://docs.orchardcore.net/en/latest/reference/modules/Recipes/#recipe-migrations
