Place the eggs in a medium saucepan and cover with cold water by at least one inch.
Bring the water to a rolling boil, then immediately cover the pan and remove it from the heat.
Let the eggs sit in the hot water for 12 minutes, then transfer them to an ice bath for 5 minutes to stop the cooking process.
While eggs cool, cook the bacon slice in a skillet over medium heat until very crispy, then drain on a paper towel and crumble into small bits.
Peel the eggs carefully and slice each in half lengthwise.
Remove the yolks and place them in a small mixing bowl, setting the whites aside on a serving plate.
Mash the yolks with the Greek yogurt, Dijon mustard, sea salt, and black pepper until the mixture is completely smooth and creamy.
Pipe or spoon the yolk mixture back into the centers of the egg white halves.
Garnish each deviled egg with a dusting of smoked paprika, fresh chives, and the crispy bacon crumbles before serving.
