The most important thing to balance the Vaat is tila tailam or seasame oil. If you keep your bowels free. Then you can expect that Vata can be balanced.
Sonth or dry ginger powder along with a pinch of rock salt with warm water can also be used to decrease the effect of Vata
Oils such as ksheerbala tailam, Dhanvantari, tailam and kottam chukkadi tailam will be helpful for external application
Next Steps

There is a good quotation from Ayurvedic text or Samhita

दोष साम्यम आरोग्यता
vitiation or imbalance of dosha causes diseases and on the contrary, the balance of dosha causes proper health.
