For the 2006 anniversary several Italian books were published. Two are 1706: L'Assedio di Torino by Dario Gariglio; and "A Me I Miei Dragoni!" Torino 1706 Il Piemonte Sfida Il Re Sole by Fabio Fiorentin. You might be able to find some web sites for it too. (I know I found some reenactor sites although they mainly seemed to be mid-century ones.)
This web site might also help:

And there may be a Nafziger OB for the battle or the siege. (I know there are ones for the general area like "Imperial Army in Northern Italy" sorts):

There's this from Fabio's book that I believe are the Austro-Piedmontese forces besieged in the town itself:
Piedmont:
Foot Guards 2 btns 1,212 men
Savoy line infantry 1 btn 576
Fusiliers line infantry 1 btn 540
Monferrato line infantry 2 btns 1,170
Piedmont line infantry 1 btn 350
Saluzzo line infantry 2 btns 860
Cortanze 1 btn 490
Maffei 1 btn 490
Trinita 1 btn 500
St Nazar 1 btn 490
Desportes foreign infantry 1 btn 413
Du Meyrole foreign infantry 1 btn 440
Schulemburg foreign infantry 1 btn 450
8 btns of Militia 2,500
Miners 50
Imperial hussars 500?
6 Imperial btns 1,500 [Kreichbaum; Regal; Wetzel; 1st & 2nd Max Starhemberg; Daun]
For 30 btns totalling 12,531 men
There's also a series of schematic uniform plates that show the following regiments' uniforms (and acts as an OB in its own way) that I think are from the battle:
Piedmontese: Foot Guards, Saluzzo, Savoy, Piedmont, Monferrato, Aosta, Crocebianca, Nizza, Trinita, Schulemburg foreign, and Reding foreign infantry; and the Artillery. Mounted Guardie del Corpo; Royal Piedmont and Savoy cavalry; HRH's Dragoons and the Genevese and Piedmont dragoons.
French: Dauphin, Piedmont, la Marine, Auvergne, Medoc, Bourgogne, Bretagne, Isle de France, Fitzgerald Irish (red coat and vest with white vest lace loops; white cuffs, small clothes and metal that I thought I'd describe as they aren't part of the better-known Irish Brigade) and the Soir Walloons (all white with green cuffs and yellow metal). Royal Roussillon, Royal Carabiniers, Cuirassiers du Roi, Chastelet, and Conty cavalry. Dauphin, Fimarçon, 1st Languedoc, Pézeux, and d'Hautefort dragoons.
Austrians under Eugenio di Savoia: Guttestein, J. Starhemberg, Kriechbaum, Bagni, Wurttemberg, G. Von Konigsegg infantry regiments. Palffy, and Visconti cuirassiers; Sinzerdoff, and Savoyen dragoons; Viszlay hussars (bright green dolman and pelisse; red breeches; yellow hussar boots; red and green barrel sash; brown fur trim).
Imperial troops infantry regts: Prussian Kanitz, Prince d'Anhalt and Prussian artillery; Brunswick Bevern; Saxe-Gotha; Palatinate Barbo, Efferen, and Rehbinder regts. And mounted all from the Palatinate: Hatzfeld, Stolzenberg, and Frankenberg cavalry; and the Vehlen dragoons.
