Fill a highball glass or mason jar with ice, and shake together vodka, strawberry, syrup, and lemon juice over ice.
Strain into your glass, and top with club soda until the glass is full (about 2-3 oz).
Garnish with lemon or lime wedges, strawberry slices, and a basil leaf.
Note: the sweetness of this drink will vary depending on the ripeness of your berries. If your berries are early in the season and a little bit tart, you may wish to add a little more syrup, and if they're fully ripe, then you may wish to decrease the syrup.
