One of the best list of the different magical items that are know to the Awaken is on the Mage Storytellers Companion (3rd edition) on Chapter 4. Unfortunately, Talens are not covered. Neither in any other book that I have read of Mage.
Technically, if a Talen requires a Gnosis roll, and the Awaken have no Gnosis, they cannot use it, period.
Although, I will treat it exactly as a Fetish (since is kinda like a low power fetish, as a Spirit is still inside the item), and good for us, in the mentioned book, we have rules for the Awaken and Fetishes.
The book goes on lengths on how the Awaken can create and use Fetishes, but basically you have to command the Spirit (I believe, from the top of my head, that that is Spirit 2) to let you use it. Due to the nature of how Shapeshifters create these objects (by ancient spirit pacts) and how the Awaken are NOT covered by these pacts.
This goes, I think, quite well mechanically, since a dice roll is still required to activate its powers. On the other hand, since it is a present, you may want to change the "command" to just "ask the Spirit nicely" (I believe it is still Spirit 2 either way).
I will not treat it as an Artifact (Wonders in 3rd edition are use for "any magical item", which includes Fetishes and Talens, and a bunch of other things), since Artifacts are created by the Awaken, they have Arete values and can store Quintessence, neither of these things is very much Werewolf-wise related.
